TRANSPARENT CLOSURE FOR CANS.

Specification of Letters Patent.

Patented July 1, 1919.

Application filed April 11, 1919. Serial No. 289,311.

To all whom it may concern:

. and figures of reference marked thereon,

which form a part of this specification.

This invention relates to new and useful improvements in transparent closures. for

cans and receptacles of various kinds, and affording a means which is thoroughly sealed and through which the contents of the receptacle may be seen.

The present invention consists of a simple and efficient device of this character having various other details of construction, combination and arrangement of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of -this application, and in which:

Figure 1 is a sectional view of the invention showing the parts disassembled.

Fig. 2 is a sectional view showing the parts fastened together, and

Fig. 3 is a top plan view.

Reference now being had to the details of the drawings by letter:

A designates the top of a can preferably of metal, and having a circular outlined opening formed therein, the marginal edge of which is bent to form a flange B curved as shown in Fig. 1 of the drawings, previous to the application of the transparent cap D, which is made of glass, celluloid and so .forth. When it is desired to apply the cap,

a gasket of any suitable material E is placed upon the curved end C of the flange B and the inwardly curved flanged edge F of a ring Fis interlocked with the curved flange B, the ring passing about the marginal edge of the transparent closure D, after which pressure. is applied to the interlocked parts, compressing the same so that they will assume the position shown in Fig. 1 of the drawings.

l/Vhen the parts are interlocked as shown in Fig. 2, it will be noted that the flanges are tightly pressed in interlocked relation with the gasket intermediate one of' the flanges of the. under surface of the closure, with the upper edge of the ring bearing against the outer face of the closure and flush with the top of the can, thus affording a hermetically sealed joint.

By the provision of a closure cmbodying65 the features of my invention, it will be note that a means is afforded whereby the contents of a receptacle or can may be visible for inspection at any time and still affording a secure means for preserving the contents air tight.

What I claim to be new is:

In combination with a can having a flange about the marginal edge which is downwardly and upwardly curved, a gasket resting upon said edge, a window resting upon said edge, a ring having a curved flange interlocked with the curved flange upon the top and bearing against said window and holding the same in a clamped relation against said gasket, the upper face of the ring and the top being flush.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
